Estadio Unión Tarma

Estadio Unión Tarma serves two clubs at once, ADT and Sport Dos de Mayo, an arrangement more common in smaller Peruvian provinces than in the capital, where grounds tend to belong to a single tenant. The ground's own history runs through a rebuild: opened in 1980 with room for 6,000, it was reworked in 2022 and now holds 9,100, a capacity gain that outpaces most stadiums of its era in the region.

The pitch itself sets it apart from the older grounds nearby — artificial turf, laid down for year-round consistency at altitude, where Tarma's climate can be unforgiving on natural grass. The address on Jirón Tacna places it within the town rather than on its outskirts, keeping it a walkable fixture for both sets of supporters rather than a weekend drive.
